SOLVING BY COMPLETING THE SQUARE AND THE QUADRATIC FORMULA WORKSHEET

Solving by Completing the Square and the Quadratic Formula Worksheet :

Here we are going to see some practice questions on solving quadratic equations by completing the square and quadratic formula.

Solving by Completing the Square and the Quadratic Formula Worksheet - Practice questions

(1)  Solve the following quadratic equations by completing the square method

(i) 9x2 −12x + 4 = 0

(ii)  (5x + 7)/(x - 1)  =  3x + 2

(2)  Solve the following quadratic equations by formula method

(i) 2x2 −5x + 2 = 0

(ii) 2f2 −6f + 32 = 0

(iii) 3y2 −20y - 23 = 0

(iv) 36y2 −12ay + (a2 −b2) = 0

(3)  A ball rolls down a slope and travels a distance d = t2 −0.75t feet in t seconds. Find the time when the distance travelled by the ball is 11.25 feet.       Solution
